IMPROVENINTV IN PUMP-BOXES.

The Schedule eferred to in these Letters. VPatent and making part of the lame.

'Be it known'that I, ANTHONY S. Wnicrvnnot'sn of Ashland, in the county of Middlesex and State' of Massachusetts, have' invented a new "and improved Pump-Box, of which the following is a full, clear,

and exact description, reference being had' to the ac companying drawings making a palt of this specifica-` tion, and representing a transverse vertical section of a valve and valve-box 'containing my improvement.

The object of my invention is to prevent the en,-

ytrance of any dirt or other vmatter within the valve as the water is drawn through it; and,

The invention consists in 'a valve-box formingthe inverted frost-um of a cone,'in which a conicalilter is secured, with itsV apex near the Avalve at the top,

-said valve having its attachment to the upper part of said box, as hereinafter shown and described.

open the valve by mansof the lever E which i`s 'piv` ot'ed to .the support C.,

'All of the 'above are of the usual construction and f attached, in any. suitable manner, thc lower edge of a perforated plate, 1), of conical forni, its apex extending upwai'd as fitr as may be found necessary or suitable.

instead of' as perforated plate, Wire-gauze may be used ofthe same form as shown, which latter will be found to act as a ilterer to 'impui'efor muddy water.

` The inclined 4inner sides ot' the protector serve to deflect, any'dirt or foreign substance that may be drawn into the valve-box, and effectually prevent the same from passing to the valve.

Whatl claim as my invention, and desire to securel by Letters Patent, is

.A valvebox, "forming the inverted frustuin of a cone, in which a conical filter is placed with its apex near the valve at the top, said valve having its attachment tothe upper part of said box, al1 substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses J. H. ADAMS,

.Mg SnG. WILBE.;
